1. A method for producing a sieve basket for receiving medical items to be disinfected or sterilized, the method comprising the steps of:
in a first processing step, producing a base plate or sieve basket base surface comprising a bottom and side walls of the sieve basket in one piece;
in a second processing step taking place prior to or after the first processing step, providing the base plate or the sieve basket base surface with apertures or holes in order to obtain a perforated initial shape;
in a third processing step taking place after the first and second processing steps, flattening the base plate or sieve basket base surface to remove warping caused by internal stresses that develop after the first processing step and/or the second processing step, producing a perforated or punched plane that is divided into a flat inner portion and edge portions;
in a fourth processing step taking place after the third processing step, producing a sieve basket shape with a raw bottom and side walls extending vertically thereto, the raw bottom corresponding to the flat inner portion and the side walls corresponding to the flat edge portions of the perforated or punched plane; and
in a fifth processing step, which takes place directly or indirectly after the third processing step, embossing the flat inner portion with at least one embossing punch, pressing the at least one embossing punch by a press onto the flat inner portion in such a way that the flat inner portion plastically adapts to the negative shape of the at least one embossing punch so that an entirety of the flat inner portion forms a three-dimensionally structured bottom.
